Controlled input/output in progress state during testcase processing

A computer system for facilitating processing within a computing environment, the computer system comprising:

• a memory;
• and
• a processing circuit in communication with the memory, wherein the computer system is configured to perform a method, the method comprising:
• obtaining a testcase for an object having one or more pages;
• and
• processing the testcase by a test infrastructure, the processing comprising, for a page of the object:
• generating a delay in the processing of the testcase for the page of the object, the delay opening a transient input/output in progress state during which one or more test operations reference the page of the object.

A computer-implemented method comprising:

• obtaining a testcase for an object having one or more pages, the testcase including a page map control structure for the object, the page map control structure specifying one or more delay parameters;
• and
• processing the testcase by a test infrastructure, the processing comprising, for a page of the object:
• generating a delay in the processing of the testcase for the page of the object, the delay opening a transient input/output in progress state during which one or more test operations reference the page of the object.
